Cyclotriphosphazene-bridged

WebCyclotriphosphazene derivatives containing a P–NHR group in the side-chain react in the presence of a strong base to form stable intermolecular bridged products. Reaction of sodium hydride with mono-spiro cyclophosphazene derivatives having a P–NH group, N 3 P 3 Cl 4 [O(CH 2) 3 NH], (1a) or N 3 P 3 Cl 4 [CH 3 N(CH 2) 3 NH], (1b) leads to formation … WebNov 5, 2024 · The nature of cyclophosphazene-adducted compounds usually depends both on the phosphazene base and the corresponding Lewis acid. For example, for the N 6 P 6 (NMe 2) 12 .CuCl 2, Lewis acid is not bonded to a particular ring atom. However, it is located on the ring and is attached to more than one nitrogen atom [ 27 ].
